Castelli Endurance 3 Cycling Bib ShortsWith the top-end Progetto X2 Air seat pad at their core and muscle-supporting fabric, the Castelli Endurance 3 Cycling Bib Shorts deliver outstanding comfort for your longest bike rides. When it comes to on-the-saddle support and long-ride comfort, it doesn't get much better than the Endurance 3 Cycling Bib Shorts. Using their Endurance Evolution fabric, you'll find your hard-working muscles are gently compressed and supported, helping fight off fatigue for longer. It's also excellent at dealing with perspiration, preventing you from feeling cool and clammy from sweat build-up. Castelli's GIRO³ leg grippers prevent the shorts from riding up and give a smooth and streamlined finish. The fit of the Endurance 3 shorts is also exemplary. The designers at Castelli have placed the seams precisely to give a perfect fit around the hips and waist. At the same time, the panels are tailored to allow easy movement, letting you pedal smoothly and manoeuvre abut your bike with ease. Progetto X2 Air Seat PadInside the shorts, you’ll find Castelli’s premier Progetto X2 Air seat pad.
